Your working document will be the one you just saved.	This will prompt you to save a 'copy' using the same dialog box as 'save as'. You will have the ability to change the file name and/or location. If you choose the same file name and location it will over-write the original. If you changed the name or location of the document you will be working on the original document not the copy. This means that if you make additional changes and then hit save the original will be overwritten with the new changes, but the copy you saved earlier will be left at the state of the "Save A Copy".
